Hi Folks, I would like to have your opinion here
Deep sleep cycle it fine to reduce the power consumption, but the ESP must remain on during the watering cycle.
how you calculated the battery capacity/pump consumption/solar panel?
Iām looking around to select the hw
Materials List
1st pass at materials list. May not be complete yet. I included a few extra links to things like soldering equipment and crimping kit I have.
Get a good ESP32 for this project. Get one optimised for low energy / deep sleep with battery connections. Tried other boards but idel current too high.
Sensor power is supplied / managed via the power manager (not the esp32)
Iām not sure if the way all my grounds are linked is optimal, but it seems to work.
Iād suggest getting everthing except for the sensors connected and working first (including the voltage divider), and then add the sensors / pump one by one and test that they are working.
Set a short deep sleep cycle of like 30 sec on 30 sec off etc during testing.
I2C can be fussy and not keen on long wires. Solder at least on the sensor sides (dupont on other end ok? ).
It would be kickass if there was a google doc where everyone building this collaborately could document the step by step. Why hasnāt anyone done this yet?
You can be the first;) Itās not done because no-one has done it;)
Some of my projects where I donāt think there would be too much interest I tend to lag a bit on the detailed documentation and just do it a bit more āon demandā.
Documentation contributions welcome though.
Sometimes itās worth just dumping stuff to help close the gaps on a thread like this and then that can help build the how-to. Like I did that kind of thing over here.
I just had to drop you a line to express my immense gratitude for sharing this projectāitās like stumbling upon a hidden gem in a digital treasure trove! Seriously, itās been an absolute game-changer for me in getting to grips with ESPHome.
Your coding finesse has me in awe, my friend. Iām diving deep into your code, uncovering new approaches, and soaking up knowledge like a sponge. Itās like a thrilling adventure, and your project is the map leading me to programming enlightenment!
Thanks a million for your generosity. Letās keep this coding journey rolling!
I assure you itās really more of an assembly of other peopleās work on the forums which I learnt and put together one brick at a time, rather than great programming skills on my part.
Iāve been contemplating which of my deep projects I can use your new trick on BTW;) Thereās always more to learnā¦
Donāt sell yourself short, buddy! Researching, understanding, assembling, and creating something new is commendable. Incorporating the knowledge and reasoning of others into our own is a very dignified way to learn and grow. Iām sure your ability to gather and apply othersā ideas is an impressive skill in itself.
I want to thank you again for sharing this project with us. Itās shedding light on many aspects that were previously elusive to me, and Iām thrilled to see how I can apply these new insights to my own projects. Your contribution is truly inspiring and valuable to me.
Hi there. I got the esp32 with battery and also wanted to monitor the battery status. I am using the battery code and noticed the update_interval is set to never. Is there something else I need to add because the battery voltage and percent stays unknown. If I set the interval to some seconds, it displays some values.
